Once your battery powers up, you will see "HELLO" pop up on the screen and then "System: On".

The next screen will read "New Atomizer" since the atomizer has just been installed, followed by the question: "Init Res" with "NO" selected by default. Click the Right Arrow to select "YES." The battery will then analyze the initial resistance of the atomizer, and once completed will read "Init Succeed."

This will take you to your battery's Temperature Control mode with the desired temperature on display (between 200F and 700F).

Select your desired temperature by using the Right Arrow to increase the temperature and the Left Arrow to decrease it.

The first option of the next menu is Normal (Variable Wattage Mode), click the Power Button to select and activate VW mode.
